(DUGGER) - The Indiana Cyber Charter School, that recently announced the opening of its Dugger campus for the 2014-15 school year, is under fire for alleged non-payment of almost $600,000.

NewsBarbs reports, a complaint against the online charter school has been filed in the U.S. District Court's Indianapolis Division stating the school is being sued by National Network of Digital Schools (NNDS) for non-payment of services in the amount of nearly $600,000.

The complaint, which was filed on July 25, claims the school owes almost $400,000 for a loan extended to Indiana Cyber; curriculum charges totaling nearly $200,000; and $6,700 for computers and equipment.

NNDS also claims that it was erroneously charged almost $10,000 for Indiana Cyber School employee health care premiums, and that it has only received two payments for a 2012 operating contract with the online charter school.

The Indiana Cyber Charter School in conjunction with Dugger Union Community Schools recently announced plans to open a Dugger campus on August 25. The online charter serves grades K- 12 and is charted and authorized by Education One, LLC, the charter school authorizing body of Trine University.

On July 31, Don Williams, Chief Executive Officer of Indiana Cyber Charter School, announced that 275 to 300 students had enrolled at Dugger for the 2014-'15 school year, and that the charter school was following the procedure for the acquisition of the Union High School and Dugger Elementary buildings.
